面对对象案例连接数据库实例

<?php 
class mysql{
	private $host;
	private $name;
	private $pass;

	function __construct($host,$name,$pass){
		$this->host = $host;
		$this->name = $name;
		$this->pass = $pass;
		$this->connect();//这个也是必不可少的！
	}
	function connect(){
		if(mysql_connect($this->host,$this->name,$this->pass)){
			echo "连接成功!";
		}else{
			echo "连接失败!";
		}
	}
}

$con = new mysql("127.0.0.1","root","");

 ?>
